l`-invention `relates :to easement window hardware and hasfer@itsobjectionhrovideaneans `wherebyfthe "lower easement `sash may beoper- .a-ted bothasraslid-ing and as za hinged sash, under -cenditionswhich will --render l#the said sash capable of ready- `manipulationfrom-theiinside of the building Ifor raising or swinging ef the sashibut proof ragain-st lunwarranted opening fir-om the outside ofthe/building. Thus a sash Vequipped in'accordancrw-ith the present/invention lmay Abe opened toaedefinite'ly limited vex- Etenti-ier`purposes 'of ventilation, but lllockeid against further-unauthorizedopening from the {outside ofsthebuildingj-by the `same means which`provide -furthe inward swinging of the tsash'to `4facilita-te-cleani-ng or to provide directional ventilationinto -the -room shouldAthis be desired. jheeinvention l also provides a form of :hinge forl'the sash permitting the aforesaid Vmanipulation thereof and alsopermitting ready and simple detachment kof Nthe sash `from 'the frameofthe'window, such as 'for repair or replacement as'with a screen, 'forinstance.

vStill further 'the said invention vcontemplates thesprovlision o fasash hinge `affording vertical 1 adjustment as well 'as `swingingadjustment and also certain horizontally sliding'movement Ion the hingeto `facilitate `the ,c learing "of the l*frame work of the windowwhenlthe sash is swung inwardly therefrom.

Still further objects or advantages additional or subsidiary to theaforesaid objects, or resulting from the construction or operation ofthe invention as it may be carried into effect, will become apparent asthe said invention is hereinv after further disclosed.

In carrying the said invention into eiect, I may provide the lower andinner vertically slid-L able sash of a window with a plurality of hingesattaching it to one of the inside stop strips of the window frame, theother inside stop strip, on the opposite vertical edge ofthe sash, beingsevered intermediate of its height and provided with thumb screws ofsimilarly manually detachable fastenings whereby that part of the saidstop strip may be removed when it is desired to swing the sash inwardlyof the building, the said hinges being characterized by the platesthereof, which abut the sash, being vertically slotted to receive andpermit the vertical movement therein of pins entering the frame work ofthe sash, the said slots each having enlarged openings intermediatetheir length to permit attachment and detachment of the said pins to orfrom the said plates, and horizontally offset upper ends of the saidslots 22,

'=`All of which ismoreparticularly described Aand ascertained, by Way-Jef 'eX-ample, A"inand by the LAVfollowing' specic'a ion having reference to thel"aacompanying drawing, jiwherei'n: i

"I3 is :the :lower inside sash andf4 `the upper outside sashjoffthe window, fthe said -sas'hes :beingseparated 'inl sliding relation 'o `feach ether Aby fthe intermediateparting stops 45. I-B indicates the left inside stop ver Istrip ef thewindow frame and I1 the right inside stop, which in the present case issevered as by sawing at I8 from the upper portion thereof and isprovided with thumb screws I which may be manually detached from thejamb II to permit easy removal of this lower portion of the said stopI1.

Hinges, generally numbered 20, swingably attach the left'hand verticalmember of the sash I3 to the stop I6 of the jamb I0, as will be readilyseen, and it will be noted that the plates 2i of the hinges 20 whichabut the face of the sash frame are each provided with a Vertical slot22 interrupted by an enlarged opening 23 intermediate the length of theslot, through which opening the heads of studs or pins 24 projectingfrom the sash frame may be passed to permit the interlocking of the saidstuds with the slots 22 of the hinges, as will be readily understood.Thus, with the said studs 24 engaged in the slots 22 of the hinges, thesaid sash I3 is permitted movement vertically withinl the limitationimposed by the length of the said slots 22, the window being fullyclosed when the studs 24 are at the lower ends of the said slots, and,of course, partially open when the said studs are at the lower sill i2of the window frame without ob-` l jectionable friction at this point.

When the said window is so swung inwardly'of` 2,392,997 l Y, 1.5M'

the room, both sides are easily accessible for i cleaning and a clearopening provided for access to both sides of the upper sash forcleaning, there being no obstruction of the upper sash such as isordinarily experienced when the lower" sash is' raised inthe manner ofsliding easement windows as ordinarily constructed. A l

Further, if thoughtnecessary or desirablafsuitable means such as anadjustable brace 25 may be provided to secure the' s ash invariousangles of opening to which it maybe swung-, inorder to directa draft atanangle into-the room for instance, but thismeans of securing the sashin such positions of opening is not an essential part vof the presentinvention and is not described in furtherdetail as it is'obvious rthatany of many -deviceson the market may be used for such pur- IJOSG. f Y

The said sash I3 may be readily detached from its hinges, after it hasbeen partly swung out from the frame,vby simply aligning the studs 24with the enlargements 23 of the slotsrwhereupon the heads maybewithdrawn through the said enlarged openings; and vwhen the sash is sodetached from the hinges it may be openedwide .by sliding ingthe usualAmanner between its stops without the-limitations imposed by the hingesand already described The change from the free opening .to the limitedopening arrangement is quite simply effected by this disengagement of 4the hinges from thesash.

in cases where the thickness lof; the sash and -the size yand .positionof-the Ystops may impose an undesirable obstructionto the .freeswingingof the sash on its hinges, I may provide at the lower end of each slot22 a horizontal offset notch 2B permitting movement of the said studs 24laterally in to the notches 2S of the hinge plates, during the swingingof the sash, in order that corresponding horizontal movement of the sashmay take place to permit the outer vertical frame member of the swingingsash to be moved away from the jamb yIl as the swinging takes place andthus .prevent the saslnby reason of its thiiclrness,` becoming wedgedagainst theopposing 'face of the jambduringthe swinging movement. Y Thisprevents the necessity of cutting away an undue amount of the rear edgeof the right hand vertical frame member of the sash i3, as at 21, sothat a maximum true sealing or abutting surface between the said sashframe member and the jamb may be maintained when the parts are in theirclosed position.

' This invention may be developed within the scope of the followingclaims without departing from the essential features of the saidinvention, and it is desired that the specification and drawing be readas being merely. illustrative of a practical embodiment ofthe saidinvention and not in a strictly hunting sense.

YWhat I claim is:

Vl. In adevice ofthe class described, in combination, a window frame, avertically slidable sash mounted therein, a removable stop strip on,said frame for one vertical edge of said sash, and hinges on theopposite side of said frame, said hinges being characterized by pin andslot attachment to the other vertical edge of saidsash permittinglimited verticalsliding of said sash, the slots having enlarged openingsintermediate their length'whereby the said hinges may be disconnectedfrom said sash when it is partially raised within the slidingvlimitation imposed by said slots, said slots also having horizontallyoffset recesses at their lower ends,

2. A hinge to provide sliding action, swinging action, and horizontalmovement in a window sash, said hingev having a vertical slot in one ofthe plates thereof with 'an enlarged opening in PRENTIC.
